- Abstract
- High-resolution (HR) ultrasound, which has been progressing continuously in technology, has improved in aspect of
spatial and contrast resolution. The HR ultrasonography is a noninvasive, readily applicable imaging technique, which
could get static and dynamic image in real-time for various neuromuscular disorders, especially in entrapment
neuropathy. It is also a reliable tool to detect dynamic muscle movements such as fasciculation as well as muscle atrophy
in chronic myopathies or neuropathies. Although reliability of the HR ultrasonography has not been investigated in large
series of patients, different neuromuscular disorders tend to show specific changes on the ultrasound, which can be
helpful in differential diagnosis. The HR ultrasonography is an ideal tool for the clinical and research investigation of
neuromuscular system complementary to electrodiagnostic studies. This review briefly describes applicability for
various neuromuscular disorders with previous study results and the technical aspects of ultrasound and its physical
principles. Key Words: Ultrasonography, Nerve, Muscle, Neuromuscular disorder
